EXPLOSVE CHAMBER FOR GAS ENGNES.

Application led (lctobei' 1, 1923. Serial No. 665,925?.

`The present invention relates to new and useful improvements in motors.and it pertains more'particularly to turbines of the impact type.

lt is one of the primary objects of the present invention to provide anew and improved form of explosive chamber adapted to generate power foruse in connection with impact turbines. A

lt' is a further object ot the invention to construct a chamberot thistype in which a gaseous fuel is tired under pressure and exhausted fromthe chamber.

lit isa further object of the invention to provide an explosive chamberof the type above described, which will receive a gaseous fuel underpressure, ignite the same, and discharge the products ot combustion inthe presence ot a rotor of the impact type.

lt is a further object ot t e invention to provide a chamber whichWillcarr'v out the aforementioned operations automatically.

With the above and other objects in view, reference is had totheaccompanying drawings, in Whichv Figure 1 is a view in elevation,partly in section, showing an explosive chamber constructed inaccordance `With the present invention and oneiform of attachment to animpact turbine;

Fig. 2 is a longitudinal sectional view ot the explosive chamber Withits parts in a position opposite to the position in -which thev areshown in ldig. 1;

ig. 3 is a vertical sectional view taken on the line 3-3 oi Fig. 9L.

Referring more particularly to the drawings, the reiterence numeral 5designates a turbine ci the impact type, such turbine having a rotor 6carried by a shaft 7, all of which are ot conventional iorm. Leadinginto the housing ot the turbine 5 are two in- ,r take passages 8 and 9.

rEhe reference numeral l0 designates the explosive chamber, which ispreferably circular in :torni and has in its side Walls two exhaustpassages l1 and which coincide with the inlet passages 8 and 9hereto-tore referred to. 'lhe explosive chamber 10 is preferably formedwith rcn'iovable heads 13 and 11iand mounted in the heads 13 and 14, areigniting devices 15 and 16, respectively.,

At points removed :trom the exhaust passages 11 and 12 and preferablydiametrically opposed with respect thereto, the chamber is -from theinduction coil to the terminal l0 E@ provided with intake passages 16and 17, and having communication with such intake passages 16 and 17,there is an intake mani- 'fold 18, connected to a suitable source otfuel supply.

Mounted within the chamber 10, there is a sleeve 19, having tianged ends20 and 21. 'llhe side Walls ot the sleeve are provided near each endwith a circular series ot openings 22, the purpose ot which will behereinafter described. Mounted Within the sleeve 19, there is .atraveling piston 23, and such piston is provided with ports 24 and y25therein, the port 24 discharging through an opening '26, and the port 25dischargiuigy through an opening 27. l

Mounted in the head 13 of the chamber there is a sliding pin 28,carrying a switch member 29, and in the head 14 of the chamber there isa sliding pin 30, carrying' a. switch member 31. rlhe sliding pins arecontrolled by springs 32 and 33, respectively. The reference numeral 35designates a suitable source ot power, and 36 designates an inductioncoil. Leading trom the in-y duction coil 36, there is a conductor 37,which is grounded as at 38. Thereterence numeral 39 designates aconductor leading of the switch member 31 heretofore mentioned, andleading from the switch member 31 there is a conductor 41 which isconnected at its other end to the igniting device 15 carried by the headi3 ot the chamber 10. Leading troni the switch member 29 there is aconductor l2 connected, as at 43, to the conductor 39 heretoforementioned. llieacf ing from the switch member 29, there is conductorfill, and such conductor is eenAw nected to the igniting device itlmounted in the head 1st ot the chamber 10.,

1HEhe device operates in tbe tollewimn ner: lll/lith the i., arts inpositie" in l, en explosive c arge uncleL sure is admitted by Way o ,heintalre fold it, port il', port 25 in tbe pi. t and opening il?, to thespace bettree piston 23 and. the head la the cha Ils this charge underpressure is te the piston is to the ric.. A Q0 et the sleeve la. talesplace, the sleeve 19 moved t ,e right, in which position it is ovvn inQ. Simultaneously with this movement, the piston 23 engages the slidinggin f2@ and the litt

connects, through the medium o1.

29, the conductors 42 and 411. rllhis establishes a circuit to theigniting device 16 and lires the charge contained in the space to theleft of the piston in Fig. 2, and this charge passes out through theleft-hand open end of said sleeve 19, the exhaust port 12 ci the chamberl0, to the intake passage 9 of the turbine, and into the presence of therotor 6 thereof, which it serves to drive.

Referring to Fig. 2, it will be noted that immediately this action takesplace, a charge is taken in through the intake passage 16', the port 24of the piston, and by way of the opening 26 of the piston enters thespace between the piston 23 and the head 13 of the chamber. rIhispressure forces the piston to the left in Fig. 2, as soon as thepressure of the ignited charge falls below that of the incoming charge,and as the piston travels to the left, the space on the right thereofwill be filled with the incoming charge until the piston engages theflange 21 of the sleeve 19v and moves the same to ,the left in whichposition it is shown in Fig. 1, thus closing the intake passage 16 andopening thegexhaust passage 11. During this movement, the piston 23engages the sliding pin 30, and through the medium of the switch member31, completes a circuit through the conductors 39 and 41 to the ignitindevice 15, firing the charge at the right o the piston in Fig. 1, whichchar e passes outwardly through the righthan -open end of the sleeve 19and through the passage l1, by way of the intake pipe. 8, to the rotor 6of the turbine 5 which 1t serves to drive.

By reason of the circular series of openings 22, it is apparent that thesleeve 19 need not be guided in its movement since regardless ofcircumferential movement of the sleeve, a charge will always be fedinwardly of said sleeve to the proper side of the piston.

From the foregoing it is apparent that the present invention providesmeans whereby ex losive charges are intermittently presente to the rotorofthe turbine .to drive headset the saine, and that after the device hasbeen started the same is automatic in its operation and will continue tosupply the turbme with products of combustion under pressure until thesupply oir' fuel has been cut off.

What is claimed is:

1. A power impulse generator comprising a cylinder having an inlet andan outlet port at each end thereof, a sleeve movable within saidcylinder, said sleeve having a plurality of openings. passing throughits side wall at a point near each end of the sleeve, a piston freelymovable Within the sleeve and serving to reciprocate said sleeve iuresponse tothe pressure of each fuel charge entering said cylinder, saidpiston.

of openings passing through its side wall at a point near each end ofthe sleeve, a piston freely movable within the sleeve and serving toreciprocate said sleeve in response to the pressure of each fuel chargeentering said cylinder, said piston having a plurality of passagesadapted respectively to register with the inlet ports of the cylinderand the openings in the ends of the sleeve to establish communicationbetween the inlet ports and the interior of said cylinder, and meansoperating in conjunction with the inlet and outlet ports, the openingsin the sleeve and the passages in the piston for causing successiveexplosions for the purpose specified.
